- soname bumped to 51
- Update to stable version 1.6
  Perfomance changes:
  * heavy improvements for AVX2 capable platforms
    (Haswell and later Intel CPUs) and work efficiency
    improvements for multiple-socket machines.
  
  API changes:
  * --threads N replaced by --pools N,N and --lookahead-slices N
  * --[no-]rdoq-level N - finer control over RDOQ effort
  * --min-cu-size N - trade-off compression for performance
  * --max-tu-size N - trade-off compression for performance
  * --[no-]temporal-layers - code unreferenced B frames in temporal
    layer 1
  * --[no-]cip aliases added for --[no-]constrained-intra
  * Added support for new color transfer functions "smpte-st-2084"
    and "smpte-st-428
  * --limit-refs N was added, but not yet implemented
  * Deprecated x265_setup_primitives() was removed from the public
    API and is no longer exported DLLs
  
  Threading changes:
  * The x265 thread pool has been made NUMA aware.
  * The --threads  parameter, which used to specify a global
    pool size, has been replaced with a --pools parameter which
    allows you to specify a pool size per NUMA node (aka CPU socket
    or package). The default is still to allocate one pool worker
    thread per logical core on the machine, but with --pools one
    can isolate those threads to a given socket.
  * Other than socket isolation, the biggest visible change in the
    NUMA aware thread pools is the increase in work efficiency.
    The total utilization will generally decrease but the performance
    will increase since worker threads spend less time context
    switching.  Also, the threading of the lookahead was made more
    work-efficient. Each lookahead job is a much larger piece of work.
    Before (1.5):
    disable thread pool: --threads 1
    default thread pool: --threads 0
    restrict to 4 threads: --threads 4
    After (1.6):
    disable thread pools: --pools 0
    default thread pools: --pools *
    restrict to 4 threads: --pools 4
    restrict to 4 threads on socket 1: --pools -,4
    restrict to all threads on socket 0: --pools +,-
  
  Multi-lib interface:
  * In order to support runtime selection of a libx265
    shared library, we have introduced an x265_api structure
    and an x265_api_get() function. Applications which use
    this interface to acquire the libx265 functional interface
    will be able to use shim libraries to bind a particular build
    of libx265 at run time. See the API documentation for full
    details.

- soname bump
- Update to stable version 1.5
  * improvements in Main10 compression efficiency and performance
    and psycho-visual optimizations now enabled by default
  Feature additions:
  * analysis re-use features have been completed
  * rate control zones have been introduced
  * --tune grain introduced
  * deblocking tC and Beta offsets are now configurable
  * denoise is seperately configurable for inter and intra CUs
  * frame based CSV logging has been improved
  * New support for VTune task profiles
  Presets and defaults:
  * ultrafast no longer disables the deblocking loop filter
  * psy-rd defaults to 0.3   (was 0, disabled)
  * psy-rdoq defaults to 1.0 (was 0, disabled)
  * aq-mode defaults to 1    (was 2, auto-variance)
  * 4:2:2 and 4:4:4 encodes no longer generate compliance warnings
  API changes:
  * param.rc.rateTolerance has been removed and replaced with a simpler
    param.rc.bStrictCbr flag.
  * --log-level debug is now --log-level 4 instead of --log-level 3.
    A new 'frame' log level was inserted at level 3 in order to support
    frame level CSV logging without also enabling frame level console
    logging. Using the string name 'debug' is unambiguous as its
    behavior has not changed.
  
- version 1.4
  * large refactoring in the analysis code
  Feature additions:
  * --pmode (parallel mode decision)
  * --pme (parallel motion estimation).
  Presets and defaults:
  * --amp is now respected in RD levels 2, 3, and 4 (previously only
    in 5 and 6).
  * --b-intra is now respected in all RD levels.
  * --fast-cbf, which has only ever effective at RD levels 5 and 6,
    is no longer enabled uselessly in the fastest presets.
  * --weightb is now enabled by default at presets slower, veryslow,
    and placebo.
  * --cu-lossless was changed to only attempt a lossless encode of
    the best lossy encode method. This made --cu-lossless a much less
    expensive encode option to have enabled, and hopefully made the
    feature more robust and maintainable.
  * The upper threshold for --psy-rdoq was raised to 50 (from 10)
    since the higher values were found to be beneficial for sources
    with high frequency noise (film grain).
  * The default thread pool size logic was updated to account for the
    addition of --pmode and --pme (if WPP is disabled but --pmode or
    --pme are enabled, a thread pool is still allocated).

- Ensure we use the proper CXXFLAGS, CFLAGS and therefore
  debuginfo packages are generated correctly.
